Brief Summary

Propolis is a natural product collected by bees to seal holes and repair structures in their hives. Recently it has attracted much attention as useful substance applied in medicine and cosmetics thanks to its antimicrobial properties. Contemporary dentistry is an inseparable part of medicine and therefore attempts were made to use propolis in dentistry, as well. Purpose of the study: to investigate the effect of propolis administered in chewing gum as compared to that incorporated in mouthwash on plaque accumulation, microbial population and patient acceptance.

Outcome Measures

Primary Outcomes (3)

  • Change in Plaque Accumulation

    All children will be examined clinically using the Plaque Control record (O' Leary, Darke and Naylor). The child will be asked to chew a disclosing tablet and let it mix with saliva for 30 seconds and spit it out. Each tooth is divided into 4 surfaces; the plaque accumulations on all surfaces will be scored. The number of positively scored units is divided by the total number of tooth surfaces evaluated, and the result is multiplied by 100 to express the index as a percentage.

    Baseline and after 2 weeks

  • Microbiological Sampling of Dental Plaque

    On the day of sampling, each child will refrain from tooth brushing in the morning, eating or drinking (except water) at least two hours before sampling time. The plaque will be collected using sterilized toothpicks. Two plaque samples will be collected from each child. Anteriorly, this will be gathered from the buccal and palatal surface of the upper incisors and canines. While posteriorly, the plaque sample will be collected from the upper and lower molars. Finally, each plaque sample will be inoculated in separate vials; each vial contains 1 ml sterile brain heart infusion broth and will be sent to the lab. After 14 days, another plaque sample will be collected as previously mentioned.

    Baseline and after 2 weeks

  • Assessment of Patient's Acceptance

    Using Visual Analogue Scale (VAS).Each patient will receive the scale form and instructed to place a vertical mark according his or her personal rating of the preparation received during the treatment period on a horizontal line scaled from 0 to 10 where 0 presented for unacceptable and 10 for acceptable.

    After 2 weeks of treatment

Study Arms (2)

Propolis chewing gum

EXPERIMENTAL

2 % pure raw propolis, 20-35% gum base, 2.5% flavors, 0.3% sorbitol and 0.3% coloring substance. Children will be instructed to chew the specially prepared propolis chewing gum for at least 20 minutes, twice daily, after breakfast and before bedtime.

Combination Product: Propolis chewing gum

Propolis mouthwash

ACTIVE COMPARATOR

The formulation includes 2% pure raw propolis, 40 ml flavors, 150 ml propylene glycol, 60 gm sorbitol, 0.1 g coloring substance and water. Children will be instructed to rinse using the prepared propolis mouthwash for 1 min, twice a day, after breakfast and before bedtime.

Combination Product: Propolis mouthwash

Interventions
